test: modify estimation of tip for Devnet

[PhilippeR26]

Motivation and Resolution

When executing the test suite in Devnet, we have a flood of tip error messages.
Devnet is starting from block 0 (no history of transactions) and creates a new block at each transaction. So, the default maxBlocks and minTxsNecessary are not adapted for Devnet.
This PR create a small initiial history of Devnet transactions, and is changing the default values (only for Devnet)

Development related changes

• if Devnet is just launched (zero blocks), 3 random transactions are created, with random tips, to create an initial tip history.
• account.getEstimateTip() is overwritten when using Devnet, to use new default values:

minTxsNecessary: options.minTxsNecessary ?? 3,
maxBlocks: options.maxBlocks ?? 10,

• To create these 3 new transactions before launching the test suite, some parts of tests/config/fixtures.ts are necessary, but Jest do not accept at this stage code including the use of subscribe. So the file has been splitted in 2 files: fixtures.ts & fixturesInit.ts.
• When tip is estimated out of an account, the logger has been temporary set to critcal.

Tested with success in:

• New Devnet
• Devnet with history
• Testnet

Note

• wording of devnet-rs replaced by starknet-devnet.
• prettier has automatically modified some documentation files.
